Gallium-nitride power transistors occupy a unique performance niche. Here is why, along with five GaN devices to consider for your next design. 1. A graph from “Comparative Study of Optimally Designed ...

Linear regulators use an internal transistor to control the output voltage. That transistor needs some headroom—you can’t get 5-V output with a 5.01-V input. That headroom is also called dropout.
